It will also be noted that in the pres- 10o ent instance the ingredients are all mixed and but one operation relative to the saturation of the fibrous material is all that is necessary to place said material in the proper condition to be wound on a pile or used as a protective covering for timbers Wherever desired.

A protective covering for piles, dac., the same comprising a ibrous material combined with magnesium chlorid and oalcined magnesite, substantially as described.

In testimony whereof I hereunto afix my signature, `in the presence of two witnesses, this 1st day of March, 1898.
